BMW 328i (E46) review: the six-cylinder E46 to actually buy from this era
3.7/5motorssouq Editorial Team
If you are shopping the pre-2000 E46 six-cylinders in Bahrain, the 328i is the one to buy over the 323i: the extra 23 hp and 35 Nm are noticeable in daily use, the M52TU's Alusil block sidesteps the Nikasil problem entirely, and the price difference on the used market rarely reflects the gap in ability. Have any candidate inspected by an independent BMW specialist for cooling-system and VANOS condition before buying.
Pros
- 193 hp and 280 Nm give it meaningfully more usable pace than the 323i sold alongside it
- Alusil-block M52TU carries none of the older engines' Nikasil bore-wear risk
- E46 chassis remains a benchmark for steering feel and balance
- Priced close to the weaker 323i on Bahrain's used market despite the performance gap
Cons
- Plastic cooling-system parts rarely survive a Gulf summer without replacement by this age
- VANOS solenoid rattle on cold start is common and needs specialist attention
- Sun damage to interior plastics is typical on outdoor-parked examples
- Two-year production window limits how many good examples are left
The 328i sat at the top of the E46's engine range for its first two years on sale, a 2.8-litre M52TU straight-six making 193 hp and 280 Nm, mated to a five-speed manual or automatic and rear-wheel drive. BMW replaced it with the 330i in the late-2000 facelift, but the pre-facelift 328i has aged into a genuinely likeable used buy in its own right, not just a stepping stone to the car that followed it.
What sets it apart from the 323i
On paper the difference between the 323i and 328i looks modest: half a litre of displacement, 23 more hp. On the road it is more noticeable than the numbers suggest, particularly with the automatic gearbox, where the extra torque means the car does not need to work as hard to get up to Bahrain's typical dual-carriageway cruising speeds. Both engines share the same Alusil-block M52TU architecture, so the 328i carries none of the Nikasil bore-wear risk that affects the earlier E36 sixes.
Inside, the E46 cabin was a genuine step up in material quality over the E36 it replaced, and it still feels solid today if the car has been looked after, though sun-baked dashboards and cracked door-card trim are common on Bahraini examples that spent years parked outdoors.
Buying and keeping one in Bahrain
Two known weak points to check on any E46 six by this age: the plastic cooling system components, such as radiator end tanks, expansion tank and water pump impeller, that were never designed for a quarter-century of Gulf summers, and the VANOS solenoids, which cause a rattling cold start when their seals harden. Both are known, well-understood fixes for an independent BMW specialist and neither should be a deal-breaker on a car priced accordingly, but factor the cost into your offer.
